Specification of Letters Patent.

Patented June 6, 1916.

Application led December 1, 1914. Serial No. 874,978.

To aZZ whom it may concern.'

Be it known that I, MAURITZ OLSON, a citizen of the United States, residing at Bridgeport, in the countyof Fairfield and State of Connecticut, have invented certain new and useful Improvements in Counterbalanced Supports for Wire-Reels, of which the following is a specification.

This invention relates generally to wire and metal reels for supporting the reel of wire in connection with wire working machinery, and the objectA of my invention is to provide a counterbalance vreel so that a coil of wire can be quickly and easily placed upori the reel and then moved to its proper position with reference to the wire working machine.

Heretofore wire supporting reels have been constructed in such a manner that more or less diiiiculty has been encountered in placing .the heavy coils of wire either upon the reel or in positioning thereel after the coil has been placed thereon, and it is with the object of overcoming this diiliculty that I have provided a reel which can be turned down to a position convenient for the placing 'of the coil of wire thereon, and then easily moved back to its proper position.

With this object in view my invention consists essentially in providing ,a counterbalanced support for the wirereel together with suitable locking devices forv holding said reel securely in either its working or adjusting position. v

' My invention consists lalso in certain details of construction whereby the operation ofthe various parts is rendered quick and eas 'ISlhe invention also includes certain details of construction-and noveltisof combination hereinafter more fully described and pointed out in the claims. I

In the drawings forming part" of this specification Figure 1 is a perspective view "of counterbalance reelconstructed in accord- Y ance with my invention, the reel being tilted -to the coil receiving position.. Fig. 2 isa sectional elevation, the` reel being shown 1n its horizontal or working position.l Fig. 3

is a vertical sectional view showing the positions` of the various parts when the reelis tilted to receive the coil of wire. Fig.4- is a similar view'showing the positions of the various parts when the reel is lifted to its' handle as shown at A10.

working position. Fig. 5 is a. horizontal section on the line 5-5 of Fig. 4. Fig. 6 is a sectional view on the line 6 6 of Fig. 3, and Figs. 7 and 8 show details of construction.

In the practical embodiment of my invention I employ a base 1 having a standard 2 extending upwardly therefrom and having suitable bearings at its upper end to receive a journal 3 upon which a counterbalance weight 4. turns, the upper end of the counterbalance weight having a spindle 5 secured thereto and upon which the reel is adapted to be mounted.

The standard 2 is preferably channeled as shown, being closed at the front and open at the rear. A curved lever 8 is located within the bottom of the standard 2, the forward `end thereof extending through an opening in the bottom of the-standard and is pivoted to a lug 7 formed upon the base 1 slightly in -advance of the bottom ofthe standard and the forward end of this lever 8 is provided with ua treadle or step' 9. The upper or rear end ofthe lever is 4shaped into a suitable The lever 8 is formed intermediate its ends with a downwardly extending nose or lug portion 11 which is adapted to engage a lug 12 formed upon one side of the lower edge of the counterbalance weight 4, and when the r'eel is lifted4 and the counterbalance weight comes to its normal position the nose` 11 dropping back of the lug 12 locks the counterbalance weight-and prevents its rearward movement. The forward movement of the counterbalance weight is arrestedv by means of a stop finger 14"-y formed upon the lower forward end Iof the 'counterbalance weight and which contacts with the forward side of thestandard when the counterbalance weight is in its normal position as shown in .F ig. 4. The upper face of the lug 12 is beveled and the rear face of the nose 11 is slightly curved or rounded so that as the counterbalance weight 4 is brought down, the lug 12`wil1 ridereadily under the locking nose or detent 11, and-the lever is also provided with a slight projection 13 in ad- Vance of the nose 11 and which contacts with base 1 and prevents the lever dropping too far down and therefore holds the nose 11 in the proper position for engagement with the lu 12.

A1.1 addition to the lug 12'carried by the these lugs, the lever'is provided with a pin 16 which is carried' by a fiat spring 16 secured to one side'ofthe lever` and vextending just beneath the forward edge of the counterbalance weight 4, thereby serving, in connection with the lug 15, to hold the counterbalance weight in itsl raised or horizon-- tal position so that the reel will be maintained in its lower or receiving position, and in this position the coil of-wire can be quickly and easily placed upon the reel, and then. by virtue of the counterbalance weight, the reel loaded with a fresh coil of wire can be shifted back to its normal working position. In addition to the inclined face 14 the lug also has an inclined face 14 which contacts with` the inclinedface 15 of the lug 15 when the reel is pulled down and the counterbalance weight v4 raised and the lug 14 is thus caused to ride along the lower edge of the lug 15 throwing the lever 8 forward until the lug 14 passes the lug 15, and the lever dropping back will then bring the face 15 in contact with vthe face 14 as previously stated.

then use both hands for returning the reel,

and inasmuch as this groove 17 -is gradually tapered toward its vinner end the pin will be gradually forced back and carried out of the groove, the counterbalance being fully released and moving toward its normal lower position. As the counter weight descends the lug-12. drops beneath the nose or pawl 11 j and thereby becomes securely locked. The\counterbalance can be unlocked either by pressing upon the treadle 9 or pulling upon the handle 10 as previously stated.

The reel comprises a hub 18, arms or spokes 19 and a 'rim 20; the hub 18 resting upon a sleeve 21,y and secured by means of a collar 22.

ln practice lprefer to construct the sleeve 21 withastub aXle 23 extending at right angles therefrom and upon which the reel hub amaca? can be mounted .if it is desired to support the reel in a vertical instead of a horizontal position. j

A Upon the spokes 19 arevmounted the adjustable arms 24 provided with suitable fastening means, and each arm 24 is provided with adjustable fingers 25, the coil being arranged upon the spokes and held in position lby the arms 24 and fingers 25 being clamped against the coil;the coil 'being indicated in dotted lines in Fig. 2.

It will thus be understood from the above description in connection with the accompanying drawings that I" provide a support for the wire reel which can be quickly and easily pulled down to a receiving position for the purpose of having the coil of wire placed thereon, and then as easily returned to its normal. Work-position, by virtue of the counterbalance weight which will compensate for the weight of the coil upon the reel, the counterbalance being securely locked in its raised position when thecoil is being placed upon the reel and equally locked when the counterbalance is lowered and the reel lifted to its normal or working position.` It will also be understood that the counterbalance can be quickly and efsilyrI unlocked from either one of its above described positions.
